Introduction
This document provides the Functional Specification for the implementation of Two-Factor Authentication (2FA) within the system. It outlines the necessary requirements and considerations for successful integration.
Purpose
The purpose of this FSD is to detail the functional requirements for implementing Two-Factor Authentication (2FA) to enhance the security of user accounts within the system.
Scope
The scope of this FSD covers the implementation of 2FA in the system, ensuring that all users are required to authenticate their identity using a second factor beyond their password.
Definitions, Acronyms, and Abbreviations
- 2FA: Two-Factor Authentication
- OTP: One-Time Password
- SMS: Short Message Service
- Email: Electronic Mail

Overview
The goal of this project is to implement Two-Factor Authentication (2FA) to provide an additional layer of security for user accounts. This involves requiring users to authenticate their identity using a second method, such as a One-Time Password (OTP) sent via SMS or email, in addition to their password.
Functional Requirements
Requirement 1: Two-Factor Authentication (2FA)
- ID: FR-001
- Description: Implement Two-Factor Authentication (2FA) for all user logins to enhance security.
- Priority: High
- Source: Security Best Practices
- Rationale: To ensure the security of user accounts by requiring an additional authentication step.
- Acceptance Criteria:
- Users must enter their password and a second authentication factor (OTP) to successfully log in.
- OTP can be sent via SMS or email.
- The system must verify the OTP before granting access.
- Dependencies:
- Integration with SMS and Email services for sending OTPs.
- User database must store and manage 2FA settings.
Data Requirements
- User accounts must store the preferred method of receiving OTPs (SMS or email).
- Secure storage of OTPs with expiration time for each OTP.
User Interface Requirements
- Login page must include fields for password and OTP.
- Option for users to choose between receiving OTP via SMS or email.
- Interface for users to manage their 2FA settings.
Non-Functional Requirements
- Performance: The system must send OTPs within 5 seconds.
- Security: OTPs must expire after 5 minutes and must be securely transmitted.
- Usability: The 2FA process must be straightforward and user-friendly.
Assumptions
- Users have access to either their mobile phone or email for receiving OTPs.
- Users are familiar with the concept of Two-Factor Authentication.
Constraints
- The implementation must comply with data protection regulations.
- The system must be able to handle high volumes of OTP requests without degradation in performance.
Acceptance Criteria
- Successful verification of OTPs and user access granted upon correct entry.
- Secure and timely delivery of OTPs.
- User satisfaction with the 2FA process.
Appendix
- Example screenshots of the 2FA user interface.
- Flowchart of the 2FA authentication process.
